A) 8
B) 5
C) 6
D) 7
Correct Answer: B
Solution :
The electronic configuration of nitrogen is \[_{7}N=1{{s}^{2}},2{{s}^{2}},2{{p}^{3}}\] It has 5 electrons in valency shell, hence in ammonia molecule it complete its octet by sharing of three electron with three H atom, therefore it has 8 electrons in its valence shell in ammonia molecule \[\underset{H}{\mathop{\underset{\times }{\mathop{H\times \cdot \underset{.}{\overset{.\ .}{\mathop{N}}}\,\cdot \ \times H}}\,}}\,\] or \[\underset{\,H}{\mathop{H-\underset{|}{\overset{.\ .}{\mathop{N}}}\,-H}}\,\]You need to login to perform this action.
